HI-END preferred, E-405 reoccurrence
As is well known, audio equipment is different from computers, and its related production technology has long been mature; Its production is similar to that of musical instruments, and the quality depends on the materials and craftsmanship used, and has little to do with technological content (similar to musical instruments); For example, the sound quality and various technical indicators of an amplifier depend entirely on the manufacturing process and materials of transformers, capacitors, and amplifier tubes. The specific circuit and manufacturing form have not changed for many years. The sound quality of a speaker largely depends on the selection, texture, and materials used to produce the unit magnets. So, we are committed to exploring and restoring classic audio equipment at a lower cost, but the price is very cheap, and the effect is far better than the new fever audio equipment that costs tens of thousands of yuan at any time.
The E-405 version is the latest version based on the Golden Voice E-405 circuit design, which is a popular amplifier circuit among radio enthusiasts. This circuit features dynamic sound, wide sound field, deeper layers, and sufficient thrust. During the debugging process, a large number of imported components are used and strictly paired to ensure excellent performance. The materials used are also meticulous, with 10 pairs of Ansenmei MJL21193/ML21194 transistors used for the main tube, 2 BC67000uFX2 capacitors twice the capacity of the original machine, and 2 pairs of 2SK170/2SJ74 input stage. Its high-level positioning is sufficient to meet the needs of the Philharmonic Friends.
